Jul 23, 2018 · Is there any good library in python (if possible) which can find intersections between 3D objects? A good option is to use open-source library MeshLib , written in C++ but also having a Python interface and package downloadable by pip install .

PyMesh promotes human readable, minimalistic interface and works with native python data structures such as numpy.ndarray. Load mesh from file: Access mesh vertices: Compute Gaussian curvature for each vertex: Read/write 2D and 3D mesh in .obj, .off, .ply, .stl, .mesh (MEDIT), .msh (Gmsh) and .node/.face/.ele (Tetgen) formats.

Oct 27, 2022 · By looping over the faces (consisting of 3 points if triangles) of the mesh and checking if and where each edge (v1, v2) intersects with the plane, you will get good result, depending on your use case. See here for an implementation of …

Feb 4, 2025 · I am trying to intersect 3D and 2D Meshes with 3D and 2D elements. What I need from that intersection is the center of the intersection, and the volume. I have a coordinate matrix as well as a connectivity matrix, to define the mesh, and the same goes for the element.

Aug 30, 2018 · A much easier way to get mesh-line intersections would probably be ray tests, using mesh.ray.intersects_location query rather than a cross section. I just added a simple example here: https://github.com/mikedh/trimesh/blob/master/examples/ray.py

🚀 Try MeshLib — a mesh boolean library for Python & C++ that performs union, difference, intersection, inside & outside extremely swiftly — even on 2M+ triangle meshes.

Mar 25, 2024 · Learn how to generate intersection meshes by rotating 3D geometry using Numpy and Pyvista in Python.

Oct 23, 2024 · Learn to plot 3D plane intersections using Python Matplotlib, covering two, three, and multiple planes, and highlighting intersection lines.

Feb 10, 2022 · import matplotlib. pyplot as plt isect, face_inds = trimesh. intersections. mesh_plane ( mesh, plane_normal = (0, 1, 0), plane_origin = (0,-0.5, 0), return_faces = True) plt. scatter (* isect [:, 0, 0:: 2].

Detecting & Penalizing Mesh Intersections This package provides a PyTorch module that can efficiently (1) detect and (2) penalize (self-)intersections for a triangular mesh. Table of Contents
